EV charging bays card

Supplied bay states appear with connector type, rated power, actual charging power and remaining-time estimates. Fresh, explicit availability alone counts as free, while elapsed finish estimates leave bay states unchanged. Unknown or stale readings stay marked as such. Primetime treatment brings staggered tile entrances, slow pedestal-and-cable linework and restrained fault outlines.

Data and privacy

This card uses its configured properties and live card data.

Bay states and charging telemetry; no driver or vehicle identity is required.

Properties

For theme, background, accent and position, see Common properties.

Set static properties in params. Bind data to a project card data key for live values; that document holds only dynamic properties. Without a data key, put the complete configuration in params. Nested rows describe the contents of their parent property.

Static properties

Name	Type	Default	Values and limits
`staleMinutes`	integer	`5`	minimum: `1`; maximum: `1440`
`perPage`	integer	`12`	minimum: `4`; maximum: `24`
`pageSeconds`	integer	`12`	minimum: `8`; maximum: `120`

`updatedAt`	string	`""`	maxLength: `64`
`note`	string	`""`	maxLength: `240`
`bays`	array	`[]`	maxItems: `120`	Explicit bay states. Only a fresh available state counts as free; an estimate expiring never frees a bay. First duplicate id wins.

Canvas example

Add this item to a playlist page’s primitives. Publish the playlist and assign a screen.

{
  "id": "ev-chargers",
  "primitive": "card",
  "card": "ev-chargers",
  "major": 1,
  "params": {
    "theme": "neomustard"
  },
  "rect": {
    "x": 0,
    "y": 0,
    "width": 1920,
    "height": 1080
  },
  "layer": 0,
  "content_fit": "fill",
  "data": "example-key"
}

Write live data

The canvas example binds its data field to example-key. That value is a data key: a name this canvas item chooses, not the name of the card. Give each canvas item its own key when items should show different data, or share one key when they should show the same data. Keys are scoped to the project, follow the K/V key grammar, and cannot start with feed:.

Create this document before showing the card, then replace it to update the screen without republishing. Writes to a key that live canvas items bind are checked against each bound card’s dynamic properties. Use the same project as the playlist.

Save the document as card-data.json. The CLI reads the document itself, with no wrapper:

{
  "title": "EV charging bays",
  "site": "",
  "updatedAt": "",
  "note": "",
  "bays": []
}

screenrig card-data put example-key --file card-data.json

Or call the API directly. The API wraps the same document in a document field. An agent token already names its project, so no project header is sent; if you send ScreenRig-Project, it must match the token’s project. Supply your API authorization through the environment; see API authentication.

curl --request PUT "https://api.screenrig.ai/api/card-data/example-key" \
  --header "Authorization: Bearer $SCREENRIG_TOKEN" \
  --header "Content-Type: application/json" \
  --data '{"document":{"title":"EV charging bays","site":"","updatedAt":"","note":"","bays":[]}}'
